PSP Nmaped

Just by mere curiosity I ran nmap to check my PSP ports and this was the result:

While browsing a site

Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2005-10-09 01:47 WEST
Interesting ports on 192.168.2.120:
(The 3138 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE VERSION
67/tcp filtered dhcpserver
67/udp open|filtered dhcpserver
68/udp open|filtered dhcpclient
MAC Address: xx:xx:xx:xx:xx:xx (Sony)

Nmap finished: 1 IP address (1 host up) scanned in 6.573 seconds

I was expecting more open ports, the DHCP server must be used when playing games in AD-HOC mode.
